How Does An Air Compressor Heat Recovery System Work?

An air compressor heat recovery system works through a series of processes:

Firstly, as the air compressor operates, it generates heat due to the compression process. This heat is present in the lubricating oil and the compressed air itself.

A heat exchanger is a key component in the system. The hot lubricating oil or compressed air passes through one side of the heat exchanger, while a coolant or a fluid intended for heating passes through the other side. The heat exchanger allows the transfer of heat from the hot side (from the compressor) to the cooler side (the target fluid for heating).

For example, if the recovered heat is intended for water heating, the water circulates through the heat exchanger and absorbs the heat, increasing its temperature.

The heated fluid can then be used for various purposes. It could be sent to a hot water storage tank to supply hot water for industrial processes, space heating in a building, or even to preheat incoming water for other systems, reducing the energy needed for subsequent heating.

The efficiency of the heat recovery system depends on factors such as the type and size of the air compressor, the operating conditions, and the design of the heat exchanger.

Continuous monitoring and control systems are often employed to ensure optimal performance and to adjust the heat recovery process based on the changing demands and conditions of the facility.
